Advice
Reason
Recycling
It cuts up to 1,000 pounds of annual carbon dioxide
emissions that contribute to global warming.
Replace 75-watt incandescent bulbs
It cuts 75 pounds of carbon dioxide emissions per year,
with 19-watt CFL ones
and you save money on your energy bill.
Use a dishwasher - on full loads only
It uses up to 50 percent less water than washing by hand.
Use green cleaners
Conventional cleaners are filled with chemicals that
damage aquatic life when they go down the drain.
Take your own bag when you go
Remember that paper bags consume four times as much
shopping
energy to produce as plastic bags and they generate 70
percent more air pollution during manufacture.
Don't use a car
If you walk or use a bike, you will cut down on your
environmental impact, you will save money and it’s also
healthier!

[S.: speaker; M.: Mayor]
S. Good Evening everyone and welcome to tonight's edition of Living World. We have a very
special guest with us this evening, it's London's Mayor.
M. Hello, I'm delighted to be here.
S. I've read recently that you want London to be the 'greenest city' in the world and to lead the way
on climate change. How are you going to do it?
M. My plan is to launch a Climate Change Agency for London that will make it the most
environmentally friendly city in the world.
S. What would the agency do?
M. My hope is that the agency will help to cut carbon dioxide emissions by 20%. It will encourage
firms to have more energy efficient offices and design renewable energy products such as solarpowered panels and wind turbines.
S. Who is going to pay for it?
M. We have some powerful sponsors in big business, banks and Insurance companies.
S. What can individual Londoners do?
M. We can start by making homes more energy efficient and use greener energy. By 2025 I would
like 25% of London's electricity supply to be from local combined heat and power systems.
S. Why London?
M. In my opinion large, major-energy consuming cities like London have a responsibility to reduce
their carbon emissions and stop producing so much pollution.
S. How can you stop people wasting energy?
M. Londoners don't have to reduce their quality of life to tackle climate change, but we do need to
change the way we live.
S. What are the implications here?
M. Climate change is at the top of my agenda because it will impact on just about every aspect of
life in the city, from the way we work to the look of our parks and gardens.
S. Thank you for taking the time to come and talk to us about your extremely interesting plans for
climate control and energy saving. I'm sure your ideas are fundamental to a greener future and let's
hope other major cities will follow London's lead.

Speaker 1: We hear more and more these days about alternative sources of energy. Nuclear power is
cheap but there is always a risk of a nuclear accident and the waste products are very polluting. Oil
we all know is responsible for global warming. So what do we have left? Solar energy.
Speaker 2: Solar energy is cheap but unreliable unless you live in Africa. Hydroelectricity is very
expensive to set up but then cheap to run. Tidal power and wind power again rely a lot on the
elements and we don't all have access to geothermal power. So what shall we do?
Ex 26a p. 79: Student's activity. These questions aim at raising awareness about the problem of
waste and the three Rs: Reduce: This is the first action to take because reducing what we use and
what we waste means using fewer natural resources and less energy. Ways to reduce waste include
buying goods that use less packaging, sharing or renting things (like lawn mowers) that aren't
needed regularly instead of buying them, and buying household cleansers that do not contain
harmful ingredients. Reuse: Reusing items - using them twice or many times instead of just once keeps them from becoming waste. Some ideas for reuse include using glass or plastic jars after
they're empty, or taking a cloth sack with you when you go shopping. You can also give your old
computer to a school or an association. Recycle: Recycling, which means converting used items
back into raw materials and then making new products with them, preserves natural resources.
Many local councils have started recycling programmes such as paper, glass and aluminium.
Ex 26b p. 79: Suggestions: These are the Smiths' guidelines to reduce waste:
- Buy only what you need. Rent, borrow, or share items that aren't used much (for example the lawn
mower).
- Sell or donate goods instead of throwing them out (see the garage sale).
- Buy non-toxic or the least toxic products available (Mr Smith is using natural cleansers to clean
the kitchen).
- Buy products that use little or no packaging. Buy individually wrapped packages only when there
is no alternative.
- Buy reusable products, such as re-chargeable batteries that don't have to be recycled after one use.
- Buy products made from recycled materials.
- When you can't use something, find someone who can (see the woman, probably a neighbour who
has just been given a lamp).
- Take old tires to the gas station or to the local auto wrecker. Reuse them (see the child on the
swing).
- Use clean transport (see the bicycle).
- Use clean energy (see solar panels on the roof).
- Make compost (see the compost bin behind the house) with yard waste (dead leaves, grass weeds)
to return organic matter to the soil.

waste. 3. Climate change is a difficult problem and I hope we manage to solve it. 4. We are looking
forward to seeing a documentary about renewable energy. 5. One of my favourite activities is
reading. 6. He never forgave her for lying to him about stealing the laptop.
Ex 29 p. 80: 1. My mother hates getting up early in the morning. 2. Don't worry, I'm sure your
friend will get over this difficult time. 3. I finally got back the CD I had lent him two months ago. 4.
The bus didn't stop at the bus stop yesterday so I couldn't get on and had to wait for the next one. 5.
Did you know the Simons have separated? They haven't been getting on for some time. 6. I was so

PB Ex 14 p. 68: Soluzioni per il riscaldamento globale - Molte popolazioni e molti governi stanno
già lavorando duramente per ridurre i gas dell'effetto serra e chiunque può aiutare.
Ricercatori dall'università di Princeton hanno suggerito un approccio che chiamano cunei di
stabilizzazione. Questo significa ridurre le emissioni dei gas dell'effetto serra per mezzo di una
varietà di fonti con tecnologie disponibili nei prossimi decenni, piuttosto che fare affidamento su
un'enorme trasformazione in una singola area. Suggeriscono di seguire sette cunei che potrebbero
individualmente ridurre le emissioni e messi tutti insieme potrebbero tenere le emissioni
approssimativamente ai livelli attuali per i prossimi cinquant'anni.
Ci sono parecchi possibili cunei, che includono miglioramenti nell'efficienza energetica e
nell'economia del rifornimento degli autoveicoli (così meno energia deve essere prodotta) e aumenti
nell'energia eolica e solare, nell'idrogeno prodotto da fonti rinnovabili, carburanti biologici (prodotti
dai raccolti), gas naturale ed energia nucleare. C'è anche la risorsa potenziale di catturare l'ossido di
carbonio emesso dai carburanti fossili e immagazzinarlo sotto terra - un processo chiamato
sequestro del carbonio.
Possiamo anche aumentare la quantità di gas che prendiamo dall'atmosfera. Le piante e gli alberi
assorbono C02 mentre crescono, 'sequestrando' carbonio in modo naturale. L'aumento del manto
boscoso e il cambiamento del modo in cui coltiviamo, potrebbero aumentare la quantità di carbonio
che stiamo immagazzinando. Alcune di queste tecnologie hanno aspetti negativi e diverse comunità
prenderanno decisioni diverse su come produrre l'energia necessaria per vivere, ma la buona notizia
e che ci sono diverse opzioni per metterci sulla buona strada verso un clima stabile.
PB Ex 15 p. 69: 1. They have suggested "stabilization wedges" to cut greenhouses gases. 2. It
means reducing greenhouse gases emissions from a variety of sources with different technologies,
rather than relying on an enormous change in a single area. 3. They can be reduced improving
energy efficiency and vehicle fuel economy, increasing wind and solar power, hydrogen produced
from renewable sources, bio-fuels (produced from crops), natural gas, and nuclear power. 4. We can
increase the amount of gases we take out of the atmosphere. 5. There are a variety of options to put
us on a path towards a stable climate.
PB Ex 16 p. 69: 1. Will you stop making that noise? I'm trying to read this book! 2. They told me
